In a kind of mode of execution favourable equally, described motor component can have second fluid joint in join domain, and described second fluid joint is located in the following manner: described second fluid joint is aimed at the fluid output on described flange.Therefore external pipe and interface unit can be saved equally.In addition particularly advantageously, cooling action also can be extended by the fluid of percolation in the pump region of motor component or flange region, and this point again reduces motor component to the heat input in described pump, and therefore also further improves cooling action.
Certainly can also arrange for flow channel, fluid input in flange side, described fluid input and one for outside discharge conduit, the fluid output opened with flange separation combines.Equally, the fluid input opened with flange separation can combine with the fluid output of flange side.
The running through cooling initiatively and be enhanced significantly of this pump, thus effectively prevent member temperature from raising, this point particularly improves the integrity of the sealed department be made up of polymer material.During the described fuel of this external sealing, do not have steam to blow to be formed and there is no the cracking of fuel.
In addition the present invention relates to a kind of motor apparatus with common rail system, described common rail system has aforesaid grafting pump, and wherein said fluid input is connected with the pipeline of displacement fluids, and described fluid output is connected with the pipeline of admitting fluid.The pipeline of described displacement fluids and the pipeline of described admitting fluid are such as the components of cool cycles or oil circulation.
Finally the present invention relates to a kind of there is the internal-combustion engine of common rail system cool cycles or the application of oil circulation, for being cooled the grafting pump of described common rail system by the flow channel be integrated in described grafting pump.
Other mode of execution and multiple described advantage draw in view of accompanying drawing.Element shown in accompanying drawing need not illustrate with meeting ratio each other completely.
Unique accompanying drawing show in cross section grafting pump.
In the accompanying drawings, identical or that function is identical element, component, assembly or method step is marked out, as long as no providing contrary explanation with identical reference character.
Accompanying drawing shows the grafting pump 2 in motor apparatus 4, and described motor apparatus also comprises motor component 6 except described grafting pump 2, and described motor component is such as a part for engine cylinder-body or engine cylinder-body.
